I finally got Cometdocs to work. Apparently, the method they USED to use was to send you an email with a link to your converted document. That has gone by the wayside I guess. What you do now is upload your document and then haunt the next tab over (called ‘File manager’) and wait for your document to finish processing. Then, you click on the provided link and download it back to your computer. This, to me, is a much cleaner way to do it anyway.
On this tab, you are also offered the choice of leaving your original and the converted docs up there or deleting them. This is a good thing. I have found. also, that you don’t get the File Manager unless you are logged in to their site. If you are a casual user (haven’t created an account), I haven’t a clue how you get your converted document back. Maybe you don’t.
In any case, I stand corrected. I was able to convert some pesky XPS documents into something I could actually modify in a DOC format and save it.
